Important:

- BIOS version 0446 added support for Microsoft Windows 8.1. After updating to version 0446 or later, you will not be able to downgrade to version 0346 or earlier. The following warning message will display: “This BIOS is not allowed to downgrade reversion, but system will do reset in 20 seconds automatically.”
- Downgrading the BIOS to an earlier version is not recommended and may not be supported. An earlier BIOS version may not contain the support for the latest processors, bug fixes, critical security updates, or support for the latest board revisions currently being manufactured.
- Update the BIOS on your computer only if the newer BIOS version specifically solves a problem you have. We do not recommend BIOS updates for computers that do not need it.
- If a BIOS update process is interrupted, your computer may not function properly. We recommend the process be done in an environment with a steady power supply (preferably with UPS).
